A few upgrade questionsss
 

Ok, first
1) Sunroof - I hear they make like 3-4LB sunroofs for a 944 N/A, how much for one of those - that would REALLY help me in taking mine off and putting it on w/o potential damage to it.
2) Swift shift kits, do these make the shifting any SMOOTHER, like sliding into gear more easily?
4) What's the best exhaust system for a 944 N/A, performance, sound, feel, & overall looks (the only part you can see is very small LOL).
